title: [Treatment of acromegaly with octreotide, a synthetic analog of somatostatin with extended action].
abstract: Octreotide, an analog of somatostatin, is a valid tool for the cure of acromegalic disease. This compound has a prolonged half-life and is more selective than native somatostatin in suppressing growth hormone (GH) secretion. Octreotide, 100 micrograms tid sc, decreases GH levels and improves clinical symptoms in about 85% of acromegalic patients, lowering GH to below 5 ng/ml in 45% and to below 2 ng/ml in 17-21%. Octreotide normalizes somatomedin-C (IGF-I) levels in 36-50% of patients. The increase of dosage up to 1500 micrograms/day does not appear useful in poor responsive patients. No adverse effects on other endocrine functions submitted to hypothalamus-pituitary control have been observed. A slight shrinkage of the pituitary tumor is observed in 30-50% of cases. Octreotide therapy is well tolerated and side effects are usually mild. However the possibility of colelithiasis, liver damage and diabetes mellitus in patients with glucose intolerance must be taken into account. In conclusion octreotide is a useful complement to therapeutic means now used for the treatment of acromegaly.
